Does it matter? Ever been to a gig only to be let down by the order the songs are played? Eg. Slow, inappropriate song to start with? All best songs played before half way? Rubbish encore? Or does that make it more Rock N Roll? Like I said What Difference Does It Make? I reckon play best 6 songs, first and last 3 songs of set. Can't go wrong there. And don't you just hate fake encores...what's the point?? Rant over.
